This is a large bit that you'll need a full-size router with. The inserts are sharp carbide, and can easily be rotated to fresh edges when needed. It has 4x the edge life over regular router bits. The helical pattern makes a smooth cut, even in highly figured wood. The wood can be moved slowly pass this bit, and it doesn't burn.
I don't have a table saw, just a circular track-saw and this works as a jointer to edge join boards together with perfectly tight edges.
The bearings allow top and bottom template cutting when required. Very handy. They spin freely and are also wide to help prevent bearing grooves when used for flush cutting.
It can be used to cut the solid wood edging I might add to the edge of shelves.
The price may seem high, but it is ultra-high quality, with an excellent design, and the perfect size for all I need. And it will last for years to come, with easy to replace inserts.
Highly recommended!
